Specification o Application 'llcd Septembre ,To all 'Hi/ioni fit1/my conce/iin.'

lle it known that i. ilionnrzo Pnirmrr, a subject ol the King ot italy. and a resident o' ilillton'n, in the count),v ot indiana and State ot Rennsylvania. have invential. a new and funn-eveil Tool. ol" which the 'following is a i'ull. clear. and exact description.

hij invention rela tes to a combination tool and more jmrtienlarly to a tool in which wrench elements and other tools are cordiuateel with the handle ot a hammer or the like. My present in\.'eution resides in a novel wrench assembly 'l'or the rear end ot the handle oi" a hannnei' and consists in the 'lorin and arraue'enn'nt ot parts as hereinai'ter explainei'l.

Reference is to be had to thi accompanyine drawing' termine' a part oit' this lspecitication in which similar reference characters indicate coi-rospoodinn' parts in all the views. it being; und :od that the drawings are merely illuf-iti'ative ot one example ot the invention.

Fig. l a. side elevation ot a hammer equipped with in v improved wrench means;

Fig'. 2 is an enlarged loniritadinal section ol. the rear portion ot the hammer handle and the wrench means;

Fig. 3 is a il'rag'incntaijv view partly in side elevation aud partly in longitudinal section, the view being' at right angles to Fig'. 2;

Fig'. r-t is a rear end 'view oi" the improveiil tool;

Fig'. 5 is a perspective view oi the rear end ol the tool showing' a screw driver gripped between the jaws thereof;

liig. 6 is an end View ot' the hollow handle with the cap embodying' the wrench means removed.

rllhe numeral 10 designates the rear end oit a tubular handle ot a hammer or similar tool, said tubular handle being' adapted to contain miscellaneous tools such. for example, as a combination pliers 11, a doubleC ended screw-driver blade 1Q. and a, cold chisel 13. The rear end ot the tubular handle 10 is in practice provided with a bushing 111 having a polygonal interior to accommodate a polygonal nut ot a given size and a removable element 15 conforms to said polygonal bushing and is itselt formed with a polygonal interior to tit a nut olf smaller size than the bushing 14.

it cap designated `generally by the nnineral ltl :'itn'l embodying a wrench assembly f Letters Patent. Yatented 'M a1'. 5, 1918.

is removably fitted on the rear end o1" the tubular handle 10. the forwardY end 17 of said cap being' interiorly threaded to engane the externally threaded terminal 10 ot the handle. The said cap 1G is provided with wrench jaws 18, the inner ends ot which within the cap are termed with lateral tlanges 1f), said inner Vflanged ends being r eeived in a T-shaped slot Q0 in a traveler A housed within the cap. Said traveler 1s torined with torwarilly extending diametrically opposite arnls havingl thread elements 23 at the exterior thereof. and the said threaded arms are adapted to be eugagcd by a nut or ring' Q-fl tnrnable on the cap 1G, the turning' ot the nut serving' to ad "ance or retract the traveler :21 thereby Causing' the jaws 1S to be moved outwari'lly or inwardly to vary the distance therehetween tor gripping nuts of different diameters. The arms in the movement ot the traveler Q1 are accommodated in diametrically opposite slots tornied in the rear threaded end 10 ot the handle 10 and in the cap 1G. The ii'orwarilthreaded end 17 ot the cap lil is a separato member secured by screws 2G or the like. The jaws 18 ex- 'end through oblique slots or openings 27 in the rear portion 30 ot the cap 1G and the said rear portion at opposite sides ot the slot 'formed with lugs QS received in recesses Q9 in the opposite side faces oi" the jaws 18, the arrangement serving,` to steady the jaws and niale the same rigid in any given adjustment. The rear portion 30 is a separate cap piece secured hy a screw 81 or the like to the tubular body 32 oit the cap.

In addition to the function oit the jaws 18 as wrench jaws, they may be utilized for gripping` the screw driver blade 12 as indicated in Fig. 5, or for gripping the cold chisel 13. or similar tool.

Those portions of the parallel slots 25 that extend into the rear end 10 ot the handle are covered or bridged by the polygonal element l5 so that the arms 22 may pass be neath said element when moving toward the extreme forward position.

1t is to be noted also that the screw 31 extends into the path of the traveler 2l to limit the rearward movement ot the traveler.

In Fig. l the numeral 33 indicates another form ot wrench which is removably received longitudinally in the :toi-ward end 10b ot the shank oit the hammer and in the head 34 l thereof. said wrench 33 heine adated to be i?. immense locked in iositien bfv a nnt or rino' 35 as deconcurrently herewith.

l Wish to state in conclusion that although the illustrated example constitutes apraetieal eiiibedinent el? iny inrention, l do not liinit myself strictly te the mechanical details herein illustrated, since manifestly the saine can be considerably varied Without departure 'from the spirit et the invention as deiined in the appended claiins.

llaifing thus desciilieifl niy invention, ll'

elaiin as new,x and desire to secure by Letters Patent:

1. ln a teel of the class described, a tnbn lar handle; :i cap comprising a tubular body, the annular Vinner end there/eiE having threaded eiigjagenirfnt with the tubular handle, a seperate rear end ineinber en said tubular body7 and iieriniiig a closure therefor, said r-.leeiire having oblique slots, a ring' held between the said front and rear nieinbei's and foi-ined with internal threads, a screw extending transversely through the said rear ineniber and through the tubular body t0 project at the interior et the latter, jaws movable in the oblique slots and extending t0 the interior of the tubular body, and a traieler-Within said tubular bodj,r and engaging the inner ends of 1die jaws, said traveler having arms thereon formed nf'ith Y external threads engaged by the threads of the said ring, the tubular body hwing slots in which the said arms et the traveler inzty nieve in response te the turning of the ring,

and said screw constituting a stop limiting the outward movement e the traveler.

.all tool of the class described, including; a tubular handle, a'biisl'iing in the rear end of the handle, a cap on said handle7 there heini,` parallel internal slots extending in the said cap and inte the end et' the handle, the slets in the handle beingradially ontii'erd trein the said bushing, n ineniber liorining a closure ,ter the said eap, said ineinber liar'- ing' oblique slots therein, 'jaws slidable in .said oblique shits and extending Within the cap, a traveler engaging the jaws at their inner ends, arms @n the traveler moi/*able in the raid parallel slots, and a ring i'ereluble en the cap and 'formed with internal threads engaging the arms et the traveler.
